Macaroni die

Patented Aug. 12, 1930 Nrr ".ATENT ortica MACARONI DIE Application ledOctober 23, 1929. Serial No. 401,755.

The object of this invention is to provide a die for forming twistedmacaroni of the type generally referred to as Fusilli.

In the past, a very complicated die was used for making this kind ofmacaroni, and the die was so complicated and so subject to wear that themanufacturer of this type of macaroni was discouraged. Originally, thismacaroni was twisted by hand, but that process is slow and expensive. Y

My invention consists of producing Fusilli, or twisted macaroni, from adie having a straight apertured perforation therein, and so constructingthe pin that it will give to the macaroni, the desired appearance.

The following is what I consider the best means of carrying out myinvention, and the accompanying drawing should be referred to for acomplete understanding of the specilication which follows.

In the drawing Figs. 1 and 2 are fractional views of maca-` roni dies.

Fig. 1 shows in section, a one-piece die with a pin arranged therein,and

Fig. Q, shows in section, atwo-piece die with a. pin arranged therein.

Fig. 3, is a perspective view of the pin, and

Fig. 4, a pian view of the resulting material.

Similar reference numerals indicate like parts in all the figures wherethey appear.

At 1, I show the die base, and it will of course be understood that thisdie member is a plate having a number of perforations therein. Thenumber of perforations in the plate will be determined by the diameterof the plate and the diameter of the perforations.

It will be noted in Fig. 1. that the perforation wherein the pin isarranged, extends quite through the plate, but that it actually has fourdiameters. The entrance to the perforation may be bevelled, as shown at2, so as to allow a free entry into the die.

At 3, I show the larger diameter wherein the pin is introduced; for thisdiameter the perforation should be slightly tapered. The main body, orstraight portion of the pin, as shown at 4, passes through a portion ofthe perforation somewhat reduced in diameter, as

shown at 5, and the remainder of the pin passes through what may betermed the dischargey portion of the perforation, and is of a stilllarger diameter, as shown at 6.

The pin et is provided with a plurality of supporting wings, tapered toengage in the perforation 3, as shown at 7, 8 and 9. The number of wingsprovided is three, and that is the number that I have used.

I call attention to the fact that the pin that I employ in this vdie isvery much longer than the ordinary pin, and that the end of the pin istwisted on a spiral, as is shown at l0. The body of the pin serves toproduce the hole in the macaroni or spaghetti, and the twist in the pincauses the material to twist in moving the die, giving it the spiralcurl, as shown in Fig. ll.

l'his spiral is similar to the spiral which results when the roundspaghetti or macaroni is rolled on a round stick, and then the stick iswithdrawn therefrom, andthat is the effect' that is desired, for it isthat effect that produces the commonly termed Fusilli.

In F ig. 2, I show an ordinary die plate 1l, and this ordinary die plateserves to indicate the length of the pin et. It will be noted that theend 12 of the pin 4 projects beyond the bottom of the ordinary dieplate.

To protect the end of the pin, and to prevent the accidental bending ofthe pin end, I place a protector plate 13 over the pin ends, theprotector plate being provided with perforations 14, which coincide withand serve as extensions of the perforation 6 in the die body.

I show this construction of Fig. 2, so that it may be understood thatordinary die plates may be employed if elongated and twisted pins areprovided, and that is only thereafter, to provide a guard or protectorfor the protruding ends of the pins.

As previously stated, the pins may be of Y anj,T size, and theperforations in the die of any size. The pins serving to form the holein the spaghetti or macaroni, may be arranged to provide a hole ofgreater or less diameter. The pitch of the spiral may be varied so thata close or wide spiral may be had in the finished product, and othermodications may be made Within the scope of the appended claims, Withoutdeparting from the principle or sacrificing the advantages of thisinvention.

Having' carefully and fully described my invention, what I claim anddesire to secure by Letters Patent is l. A spaghetti or macaroni diehaving a plurality of perforations and arranged in each perforation, anelongated pin, a portion oi' the end of which is turned on a spiral..

2. A spaghetti or macaroni die having a plurality of perforationstherethrough, said pertorations being produced on at least threediillerent diameters, a pin supported in the largest diameter andprojecting into the smallest diameter. said pin having a portion ot itsend turned on a spiral. i

8. A spaghetti or macaroni die and a spiral pin adapted to operatetherewith for the production of spiral spaghetti.

Ll. A die for producing' Fusilli, which oonsists oi' a die plateprovided With a pluralitj7 of perforations therein, an elongated pinsupported in each perforation and projecting therefrom, said pin beingturned on a spiral and a guard plate into which all of said pinsproject.
